Introduction

Abdominal aortic aneurysm (AAA)

Each year 1000 events of death in Sweden. Since 2008 all men, at the age of 65 in VGR are offered screening for AAA.

Introduction

Wide aorta Normal aorta Irregular walls of aorta Regular walls of aorta Plaque, snaky (serpentine)

Hard to measure Easy to measure

The purpose

Explore if a gamified simulation based

nline training application could be a viable

and acceptable solution helping the screening personnel to train measuring the abdominal aortic diameter in ultrasound images.

MIE ¡2011, ¡Weronika ¡Tancredi ¡ 7 ¡

SLIDE 8

The goal

to design a usable skill training application (Aortaspelet) helping the screening personnel to measure abdominal aortic diameter in ultrasound images with better precision.

Results: Research

Results of the interviews with three stakeholders

requirements of stakeholders:
Skill training twice a year
Continuous quality improvement and control

for experienced personnel

Comparison with others

MIE ¡2011, ¡Weronika ¡Tancredi ¡ 19 ¡

SLIDE 20

Results: Research

Results of the observation of and interviews with personnel:

characteristics of the personnel
details about their work

MIE ¡2011, ¡Weronika ¡Tancredi ¡ 20 ¡

SLIDE 21

Results: Modeling

Persona – a textual portrait representing users with

similar behaviour, attitudes, aptitudes, goals and motivations

Persona Erica is a 45 years old Biomedical Analyst (BMA) that:

is confident of handling ultrasound machine
always works together with a colleague
....

MIE ¡2011, ¡Weronika ¡Tancredi ¡ 21 ¡

SLIDE 22

Results: Requirements Definition

Persona's expectations

training application should be similar to an

ultrasound machine

to rewind the sequence back and forth
to get feedback on the angle of measurement

MIE ¡2011, ¡Weronika ¡Tancredi ¡ 22 ¡

SLIDE 23

Results: Refinement

Results of usability testing of interactive prototype

Usability goal 1: (HELP markers) no one

should need help

Results of usability testing of interactive prototype

Usability goal 1: (HELP markers) no one

should need help

– What are HELP markers?

Results: Refinement

Number of times test participants needed help by task

Discussion and Conclusions

SLIDE 29

Discussion

Involvement of end-users was valuable
There is a lack of game based on line skill training

applications

Scenarios helped me as a designer to picture and

imagine different design solutions

Playing the game is still problematic

– Watching the sequence and handling the slider

at the same time is hard

MIE ¡2011, ¡Weronika ¡Tancredi ¡ 29 ¡

SLIDE 30

Conclusion

Prototype of Aortaspelet isn't fully usable yet
Material collected during the usability evaluation can

be used in the next design iteration and lead to more usable design
